Heck yeah, to everything you said, whether or not this Ebola-stricken patient used the restroom. Anything he touched, or brushed onto, very likely got his germs on it. Any coughing or sweat would have it, never mind blood or feces. All bodily fluids.
I was a microbiology lab tech when I was younger. I wore face masks, gloves, coats, hair nets, booties, etc. Washing hands nearly constantly was a given. Cross contamination was always a concern. We were very controlled and disciplined in our handling of materials and specimens.
In a hospital waiting room, there won’t be nearly the same amount of concern about contamination. I hope that changes here and now. We have a lot of new viruses entering our country.
Here we go!
